Hauv electromagnetism thiab electronics, inductance yog qhov nyiam ntawm hluav taws xob tus thawj coj tiv thaiv kev hloov pauv hauv cov hluav taws xob tam sim no ntws los ntawm nws. Nws yog aproportionality yam uas nyob ntawm cov geometry ntawm circuitconductors thiab cov magnetic permeability ntawm cov khoom nyob ze.
Cov lus nug tseem ceeb yog, vim li cas cov xov hlau muaj inductance?
Inductance hauv paus Inductance yog tshwm sim los ntawm cov magnetic fieldgenerated los ntawm hluav taws xob tam sim no ntws nyob rau hauv ib tug hluav taws xob Circuit Court. Feem ntau coils ntawm hlau yog siv raws li ib tug coilincreases lub coupling ntawm lub magnetic teb thiab ua rau kom cov nyhuv.
Tsis tas li ntawd, cable capacitance yog dab tsi? Capacitance piav qhia txog lub peev xwm ntawm ob tus neeg siv khoom, sib cais los ntawm cov khoom siv insulating, khaws cov nqi. Capacitance yog ib qho teeb meem tshwj xeeb nrog cov ntaub ntawv lossis teeb liab kab . Thaum lub teeb liab hluav taws xob kis tau los ntawm cov khub atwisted lossis coaxial hom kab , tus nqi tsim upacross lub rwb thaiv tsev ntawm cov conductors.
Xav txog qhov no, dab tsi yog inductance siv rau?
Inductors yog dav siv hauv alternating tam sim no (AC) cov khoom siv hluav taws xob, tshwj xeeb hauv cov khoom siv xov tooj cua. Lawv yog siv rau thaiv AC thaum tso cai rau DC hla; inductors tsim los rau lub hom phiaj no yog hu ua chokes.
Dab tsi yog tus kheej inductance thiab kev sib nrig sib inductance?
Tus kheej inductance yog txhais raws li tus induction ntawm ib tug voltage nyob rau hauv ib tug tam sim no-nqa hlau thaum lub tam sim no nyob rau hauv cov hlau nws tus kheej hloov. Nyob rau hauv cov ntaub ntawv ntawm tus kheej - inductance , magnetic teb tsim los ntawm kev hloov tam sim no hauv Circuit Court nws tus kheej induces ib tug voltage nyob rau hauv tib lub circuits.

XL hauv inductance yog dab tsi?
XL = inductive reactance ntawm ohms, Ω π = Greek tsab ntawv Pi, 3.142. f = zaus hauv Hz. L = inductance hauv henries. Nyeem ntxiv txog…. inductive reactance theory
Kcmil cable yog dab tsi?
Kcmil-Hauv North American hluav taws xob kev lag luam, conductors loj dua 4/0 AWG yog feem ntau txheeb xyuas los ntawm cheeb tsam nyob rau hauv phav phav ncig mils (kcmil), qhov twg 1 kcmil = 0.5067 mm². Ib ncig mil yog thaj tsam ntawm ib lub xaim ib mais hauv txoj kab uas hla. MCM-ib txhiab mais
Dab tsi yog qhov kev ncua deb ntawm fiber ntau optic cable?
2km ua Tsis tas li ntawd, qhov kev ncua deb ntawm ib hom fiber ntau yog dab tsi? Thaum ua haujlwm nrog nyob deb mus txog 2 km, siv multimode kho qhov muag - fiber ntau kab. Singlemode optical - fiber ntau cable, txawm li cas los xij, muaj ntau bandwidth-intensive thiab muaj peev xwm tsawg dua rau modal dispersion thiab suab nrov dua li multimode kho qhov muag - fiber ntau cable, txhais mus rau lub peev xwm kis tau tus mob tshaj lub nyob deb kev txwv ntawm multim
Loop inductance yog dab tsi?
Loop Inductance. Lub inductance ntawm lub voj hlau yog ib qho piv txwv hauv phau ntawv qhia ntawm lub voj voog nrog inductance. Cov kev hloov pauv siv nyob rau hauv cov cuab yeej no yog txoj kab uas hla ntawm cov hlau conductor thiab txoj kab uas hla ntawm lub voj voog. Qhov kev suav no yog rau lub voj thiab tus kheej inductance lawv yog tib yam rau qhov piv txwv no
Dab tsi yog qhov cuam tshuam ntawm qhov inductance ntawm cov zis hluav taws xob ntawm lub rectifier?
Qhov chaw inductance muaj qhov cuam tshuam loj heev rau kev ua haujlwm ntawm lub converter vim tias nws lub xub ntiag hloov cov zis voltage ntawm lub converter. Raws li qhov tshwm sim, cov zis hluav taws xob txo qis raws li cov khoom thauj tam sim no txo. Tsis tas li ntawd, cov input tam sim no thiab cov zis voltage waveforms hloov pauv loj heev
